How does the text diff tool work? ▾
The tool compares two blocks of text line by line using a diff algorithm. Added lines are highlighted in green, removed lines in red, and unchanged lines are shown for context so you can quickly spot every difference.
Can I use this to compare code files? ▾
Yes, the diff tool works with any plain text including source code. Paste the contents of two file versions to see exactly which lines were added, removed, or modified between them.
